The 2013 Consumer Electronics Show saw a strong trend in high-tech waist-trimming and tracking technology. Like the HAPIfork, an electronic fork that monitors your eating habits and helps you eat slower. Or the Fitbit. A helpful little fitness tracking wristband or clip that measures your every activity. From steps taken, distance walked, calories burned and floors climbed to activity duration and intensity, it even tracks the quality of your sleep! So you can rest easy that your workout routine is perfect.
